I started rubbing down the panels just to see what i was going to be up against, i used an electric random orbital sander with 80 grit paper (i think).



I used fiberglass matting on the inside to hold the thing together & the excess that squeezed out i flatted with the sander again.



I used this magic stuff called "Spray Putty" on all the panels, it just seemed to float on similar to that floating floor compound.







Then it was just a case of wet & dry sanding them by hand until they was all nice & smooth.

Once i had done all that, sometimes having to add another layer of putty & sanding again i was ready for my primer.











Now i know your thinking what a nice prep job i did here, well i did do a nice job according to the painter except id used the wrong primer
He said,,,,it had all started cracking, i never saw this as he never told me until after he had painted it, he said he had to rub them down & put flexi primer on the panels, id don't know if this was bullshit or the truth? i had to take his word for it & just deal with it, but i was pretty gutted after all the hard Yakka id put in sanding/rubbing them down.
So word of caution to you budding resto guys reading this, on plastic use a flexi primer (according to my paint guy).
Mezo.
